  • the length (I) from the start of the laminated core (2) to the force application point of the actuating means (7) should be as long as possible in order to be able to achieve a large actuating path (s). It should be at least 20 mm, but preferably greater than 30 mm.
  • actuating means The type of actuating means that can be used is varied. In the simplest case, as shown in Figure 1, screws can be used, but expansion bolts, motors, piezotranslators or similar elements can also be used. In principle, the travel (s) can also be generated via a fluid.

  • the advantage of the positive connection is that the flow channel height (h) can not only be reduced, but also increased. Furthermore, one is not dependent on the elastic resetting of the laminated core, so that the possible travel (s) can be even greater. In the case of sheet metal packages with large dimensions, this construction allows travel ranges (s) in the range greater than 20 mm.

For this purpose, balls (30b) are welded onto the ends of the set screws (7b), which sit in a hole in a profile strip (31b) welded to the laminated core (2b). The set screws (7b) are connected via a thread that is located in a cylinder piece (32b). The cylinder piece (32b) in turn sits in a hole in the upper part of the advertising (28b).
  • the laminated core (2b) can now be pulled up or pushed down by turning the set screws by hand or using a servomotor (1 1b).

  • the wall (2e) can additionally be adjusted locally at certain points across the width around the position set by means of the adjusting means (13e). In this case, an adjustment range of greater than 2 mm should preferably be greater than 4 mm.
  • each individual adjusting means is connected to a controllable actuator (21 or 22).
  • the thickness (y) and the width (z) of the ground path (16) must of course be continuously recorded.
  • the thickness (y) is recorded during the mass discharge with a thickness measuring system (23) and the width (z) with a width measuring system (24) and transmitted to the controller, which then carries out a target-actual comparison, determines the new manipulated variables and passes on to the actuators (21 or 22).
  • the method can be used, for example, to fill press tools with complex geometry with melt, the press tool and the discharge tool moving relative to one another.
  • the method can be used to perform a time-dependent profiling of the preform in the circumferential direction in addition to the known time-dependent profiling of the preform in the extrusion direction during the hose discharge process. This can have a significantly improved effect on the thickness distribution that arises in the blow-molded part.

Abstract

La géométrie d'un canal d'écoulement (1) peut subir de fortes variations si l'on conçoit au moins une de ses parois sous la forme d'un paquet de tôles (2), qui est plus ou moins poussé dans le canal par l'arrière au moyen d'éléments d'ajustement (7). L'ajustement peut être effectué uniformément sur toute la largeur du canal d'écoulement (1) ou seulement localement en certains points du canal d'écoulement (1). Pendant qu'un milieu circule dans le canal d'écoulement (1), il est ainsi possible de modifier depuis l'extérieur la résistance à l'écoulement dans la totalité du canal ou bien la résistance à l'écoulement en certains points, ce qui permet de modifier de la façon souhaitée la totalité du flux de matière ou la répartition du flux de matière. Grâce à la meilleure flexibilité du paquet de tôles (2) par rapport aux parois massives des canaux, on obtient de nouvelles possibilités technologiques.
